I went out to the garage and dug up my old "Handbook For Proper Crossdressing" to see what it said about this. Low and behold, there it was in Chapter 2365 (on Tolerance), paragraph 2 :
What is tolerance? It is the consequence of humanity. We are all formed of frailty and error; let us pardon reciprocally each other’s folly – that is the first law of nature.
But in the footnotes I also saw...
“A critic is someone who never actually goes to the battle, yet who afterwards comes out shooting the wounded”
